“…Phanerochaete chrysosporium exhibited high efficiency in metal biosorption during the first 15 min of incubation time . Sawdust biomass recorded the maximum removal of Ni 2+ ions within 5 min . In the present study, BM1 and BM2 achieved the maximum removal after 30 min (97.32 and 98.3%, respectively) while for BM3, the maximum removal was noted after 60 min where 95.31% of Ni 2+ ions were removed.…”

Surface properties of bacterial cells enable them to be used in the removal of heavy metals. Moreover, the inactivation of bacterial cells via chemical or physical processes may enhance the biosorption efficiency for heavy metals. The use of supercritical carbon dioxide (SC-CO 2 ) to inactivate bacteria based on destruction of cell walls took place due to the pressurized CO 2 . In this study, the pre-treatment of Bacillus subtilis cells by SC-CO 2 (BM1), steam autoclaving (BM2), and untreated living cells (BM3) were investigated to show improvement in heavy metal removal. The removal process was optimized based on the main factors affecting bacterial biosorption, which included heavy metals ion concentrations, cell biomass concentrations, pH, time, and temperature. The efficiency of bacterial biomass in removing Ni 2þ ions in the presence of different concentrations of Pb 2þ , Cu 2þ , Zn 2þ , and Cd 2þ was also tested. BM1 and BM2 exhibited the highest potential for the removal of nickel ions in comparison to BM3. The maximum efficiency was 98.54, 99.2, and 96.3% for BM1, BM2, and BM3, respectively. Moreover, BM1 displayed a higher biosorption capacity for Ni 2þ , Cu 2þ , Zn 2þ , Pb 2þ , and Cd 2þ (>150 mg g À1 ) than BM2 and BM3. Biosorption on bacterial cell biomass of Ni 2þ ions shows lower removal affinity in the presence of other metal ions.In conclusion, the pre-treatment of bacterial cells biomass by SC-CO 2 enhanced the removal process of heavy metal ions compared to untreated living cells.

“…Optimal pH of 2 to 5 has been reported by Khan et al (2004), Shukla et al (2005), and Igwe and Abia (2007). On the other hand, Habib-ur-Rehman et al (2006) and AbdelGhani et al (2007) reported an optimal pH of 6 to 6.5. Although, this study was carried out in the natural aquatic environment, the pH (6.61±0.07 -6.66±0.04) is slightly outside the reported value in the in vitro studies and may be responsible for the relative low adsorptive capacity of the sawdust in this study.…”

The impact of sawdust on the water quality of Elechi creek, in Port Harcourt municipality, has been investigated. Three sampling stations were established -upstream, vicinity and downstream of the main dump site of the sawdust in the water body. Various physiochemical characteristics, including temperature, Electrical conductivity, pH, Dissolved Oxygen, and Biochemical Oxygen Demand (BOD) as well as nutrients and heavy metal concentrations, of the water body have been measured using standard methods. The investigation reveals that sawdust may have altered the quality of water in the creek as changes in electrical conductivity and metal concentrations were observed.

“…Similar findings were reported by Ceribasi and Yetis (2001) who stated that that the biosorption process was very rapid during the first 15 min of contact time. Habib-ur-Ruhman et al (2006) revealed that the biosorption process is rapid in the initial 5 min, and further increase in contact time up to 20 min had a marginal positive effect on this process. In comparison with the sample control it was found that the natural degradation increased with time to reach 6.8% after 90 min, the removal process with the bacterial biomass cells is much better than the control, it has the ability to remove 76.85% and 49.07% by the living and dead cells within short time (10 min) which might be related to the nature of biosorption as a fast reaction process.…”

Antibiotics represent a global environmental problem due to their role in the increasing of antimicrobial resistance. Therefore, the removal of antibiotics from wastewater has received unrivalled attention in the recent years. Several technologies including the biodegradation process have been applied for this purpose. However, the potential of bacterial biomass in the biosorption of antibiotics has limited studies. The present study investigated cephalexin removal from aqueous solution by consortium bacterial cells (living and dead) which are tolerant for antibiotics. The factors including cephalexin, biomass, pH, temperature as well as presence of heavy metal ions were tested. The maximum biosorption efficiency was recorded at 0.4 mg L À1 (94.73% vs. 92.98% for living and dead cells respectively), dead cells exhibited more efficiency compared to living cells at 5 mg L À1 (82.36% vs. 46.66% respectively). Living cells are more effective at pH value between pH 4 and 6 (71.95-68.90%). The maximum removal of living cells was highest at 30°C (80.26%), while was at 25°C of dead cell biomass (63.81%). Remarkable percentage for cephalexin biosorption by living cells was recorded in the presence low concentrations of Ni 2+ (0.21 mg L À1 , 40% vs. 30% of living and dead cells, respectively). Living cells exhibited 27.42% and 25% of the removal with Cu 2+ (1 mg L À1) and Pb 2+ (0.4 mg L À1) respectively. In conclusion the bacterial cells biomass has a potential to remove cephalexin with some negative effects of heavy metals which can be overcome by the removal of these metal ions first and then removal of antibiotics in a second cycle.
